I went to exchange server , I run the best practices analyzer , and I get same errors , this is one of them :Offline address book definition is missing Server: MAIL0The 'msExchUseOAB' value for mailbox store 'Mailbox Database' on server MAIL0 is missing. This will cause offline address book errors for 6 users in this databaseI so same help in the exchange analyzer tool, but its refer to exchange 2003 steps , doesnt helpCan you please help me with this?What I done for the moment, I went to the server , I create a new offline address book , and set it up as default , I delete the first default one , but still the problem comes up.

Server Configuration --> Mailbox --> First Storage Group --> Mailbox Database (choose properties) --> Client Settings. Defineoffline address book for Information Store. Clients willfail with that error if one is not present
